Add syntax to get anvil rename text

[Henriiig]

Make it possible to somehow get the anvil rename text since this doesn't work at the moment: event.getInventory().getRenameText() and just returns when using it in a click event.

I believe this expression is already included with Skript: https://docs.skriptlang.org/docs.html?search=#ExprAnvilText

@APickledWalrus I just tested it on 1.20.6 and I can use the syntax but it still returns none when using it inside of skript-gui click event. Would be cool if this worked since anvils are very nice to use for text inputs in skripts.

Interesting it might be because it's not a real anvil. I'm not sure if there is an easy way to open a real one, but I will look into it.
